    • Artificial neural network for the classification of steel hollow pipe 

      Nur Farahiyah, Mohamad; Hafizawati, Zakaria; Rakhmad Arief, Siregar; Hariharan, M.; Fauziah, Mat (Universiti Malaysia Perlis, 2009-10-11)
      Within industry, piping is a very important system that used to convey fluid (liquid and gases) from one location to another. Steel pipe is one of the commonly type of pipe that has been used since before. Crack on pipe ...

    • Classifying material type and mechanical properties using artificial neural network 

      Intan Maisarah, Abd Rahim; Fauziah, Mat; Sazali, Yaacob, Prof. Dr.; Rakhmad Arief, Siregar (Institute of Electrical and Electronics Engineers (IEEE), 2011-03-04)
      This paper focused on experimental data and study for the testing of the material mechanical properties using vibration technique. By applying vibration analysis and testing on the material, we could determine the natural ...

    • Development of intelligent portable electronic nose 

      Abu Hassan, Abdullah; Abdul Hamid, Adom; Ali Yeon, Md Shakaff; Mohd Noor, Ahmad; A., Zakaria; Marni Azira, Markom; E.S., Tan; N.A., Fikri; Rakhmad Arief, Siregar; Mahamad Akmal, Saad (Universiti Malaysia Perlis, 2009-10-11)
      An electronic nose is a device that is able to perform electronic olfactory as a substitute to human experts. It is able to overcome the disadvantages of using human, such as fatigue and inconsistencies, as well as to ...

    • Development of Numerical Child Dummy model and the analysis of head impact criterion 

      Mohamad Sulaiman, Ibrahim; Rakhmad Arief, Siregar; Abdul Hamid, Adom; Shah Fener Khan; Hafizawati, Zakaria (Universiti Malaysia Perlis, 2009-10-11)
      This paper presents a development of numerical child dummy model and head impact criterion analysis of the numerical child dummy model. The model was developed using flexible component for crucial parts such as neck and ...

    • The effect of ASI (Acceleration Severity Index) to different crash velocities 

      Rahmad P, Nasution; Rakhmad Arief, Siregar; Khairul, Fuad; Abdul Hamid, Adom (Universiti Malaysia Perlis, 2009-10-11)
      Vehicle crash can causes severe injuries to the occupant of the vehicle. These injuries can be measured. The injury measurement is intended to insure minimum safety levels in severe crashes. There are several types of ...

    • Effect of blockage size on pipe vibration 

      Nur Liyana, Tajul Lile; Rakhmad Arief, Siregar; M.J., Hasnul; J.C., Leong (Scientific.Net, 2012-12)
      Circular pipes are widely used to convey goods to a desired location. Flow inside a pipe needs to be smoothed and unobstructed to ensure an optimize flow of particle. However, pipes are prone to clogging or blocking due ...

    • The effect of high loading rate to tensile strength for mild steel by using Hopkinson Bar technique 

      Mohd Shahiddin, Suhadi; Rakhmad Arief, Siregar; Shah Fenner Khan; Ahmad Yusri; Abd Hamid, Adom (Universiti Malaysia Perlis, 2009-10-11)
